Smile for the Dead: An Examination of Spirit Photography is a documentary that delves into the life and trial of William H Mumler, who claimed to photograph spirits of customers' deceased loved ones in 19th-century New York. Featuring interviews with historian Mark Osterman, Mumler biographer Crista Cloutier, and grief and loss expert Leslie Young-Ward, the film examines whether Mumler's methods were fraudulent or genuinely captured evidence of the afterlife.
